A No. 839,277.

Specification of Letters Patent. Application filed May 14, 1906. Serial. No. 316,843.

Patented Dec. 25, 1906.

To @ZZ whom it may concern:

Beit known that I, OzRo J. EASTON, a citi- Zen of the United States, residing at Wellsford, in the county ofKiowa and State of Kansas, have invented certain new and useful Improvements in Traction-Engines and I do declare the'following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in attachments for traction-engines, and more particularly to an apparatus by means of which the engine may pull itself out of soft or muddy places, pull a separator or the like up a steep grade, or do similar work.

The object of the invention is to provide an apparatus of this character which will be of simple and inexpensive construction, power-b ful in operation, and very convenient in use.

With the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts hereinafter described and traction-engine.

claimed.

In the accompanying drawings, Figure 1 is a rear elevation of my improved attachment or hoisting apparatus. Fig. 2 is a side elevation of the hoisting apparatus, showing the same mounted upon the rear portion of a Fig. 3 is a detail horizontal sectional view taken on the plane indicated by the line 3 3 in Fig. 2, and Fig. 4 is a detail vertical sectional view taken dicated by the line 4 4 in Fig. 2.

Referring to the drawings by numeral, 1-

denotes the base of my im roved hoisting ap aratus or attachment, w `ch is adapted to e set upon the rear of a traction-engine 2 of any form and construction. The apparatus comprises uprights 3, in the lower portions of which are journ d upper and lower transverse shafts 4 5, which are connected by a belt or. band 6, assed over band wheels or pulleys secure upon said shafts between said uprights. .The upper shaft 4 drives the lower one 5 and is driven from the line-shaft of the engine by a belt 7 passed around a pulley u on the line-shaft and about a pulley 8, whic is loosely mounted upon one end of the shaft 4. The pulley or band wheel 8 is adapted to be locked to the shaft 4 by a shdingclutch, which comprises a sleeve or collar 9, shdable upon but keyed to on the plane inu per and ...1E

. rotate with the shaft 4 and formed with projections 10, which may be moved into and out of seats or recesses 11, formed in the hub of the wheel 8.l The bifurcated end of a shifting-lever 12 engages an annular groove 13 in the clutch-head 9, so that the latter may be shifted longitudinally upon the shaft 4 to lock and release the pulley 8. The lever 12 is pivotally mounted, as shown at 14, upon a bracket-arm 15, projecting from one of the uprights 3. I

The'lower shaft 5 has secured upon one of its ends a ,worm 16, which meshes with a worm-wheel 17, loosely mounted upon a longitudinally-extending shaft 18. The latter is mounted in suitable bearings 19 upon the base or support 1 and has secured upon it a winding-drum 20. One end of a cable or other flexible connection 21 is secured to and wound upon this drum and extends downwardly through an opening in the base 1 and around a guide roller or pulley 22, mounted in suitable bearings beneath the base. The free end of the cable 21 may be attached to a separator or other object which is to be moved bythe hoisting apparatus or attachment or to an anchor when it is desired to draw the traction-engine out of muddy ground, up very steep grades, orv the-like. The worm-wheel 17 is adapted to be locked to the shaft 18-by a clutch-similar to the clutch 9. The slidably but non-rotatably mounted sleeve or collar 23 of this clutch has projections to enter recesses or seats in the gear 17 and is also formed with an annular groove to receive the slotted or open portion 24y of a shipper-lever 25. The latter has its lower end pivotally mounted in a bracket projecting from one of the bearing-uprights 19, as shown in Fig. 2 of the drawings.

The construction, use, and advantages of the invention will be readily understood from the foregoing description, taken in connection with the accompanying drawings. It will be seen that when the traction-engine is suitably anchored and the cable 21 is attached toa separator or other object the separator or object may be drawn up very steep grades or moved out yof soft or muddy spots of ground by shifting the clutch-levers 7 and 25 to throw the hoisting lapparatus into upon the drum 20. When the free end of the cable 21 is suitably anchored to a tree or IOO IOS

operation, so that the cable will be wound other stationary object and the hoisting apparatus is set in operation, the traction-engine will be moved in the direction of the anchor, so that it will be drawn up a steep grade or out of a muddy s ot.

Various changes 1n the form, proportion,

and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as dened by the appended claims.

Having thus described my invention7 what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a traction-engine and a driving-shaft thereon, of a suitable support, upper and lower shafts, a driving connection etween said upper and lower shafts, and driving connections between said upper shaft and the shaft of said tractionengine, a winding-drum, a shaft therefor, worm-gearing between the drum-shaft and said lower shaft, a cable wound upon said drum, and a guide for said cable, substantia'lly as described and for the purpose set forth. 2. An attachment of the character described comprising a suitable support, upper and lower shafts, wheels upon said shafts, belts connecting said wheels, a belt-wheel loosely mounted upon said upper shaft, a clutch for locking said belt-wheel to said upper shaft, a winding-drum, a shaft for the latter, a wormegear loosely mounted upon said drum-shaft, a worm upon said lower shaft meshing with said worm-gear, a clutch for locking said worm-gear to its shaft, a cable wound upon said drum, and a guide-roller for said cable, substantially as described and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
